When is Calibration Due?

Calibration is crucial to adjust and maintain the accuracy and precision of measuring & testing instruments.

The manufactured quality of the components, parts and products produced is determined by the calibration done on them. To ensure consistency and reliability of the measuring equipment. 
When? 

The general recommendation is an interval 12 months period.

How Often?

It depends on the:

1. Application & Overall Usage of the Equipment / System
2. Manufacturing or Industrial Requirement of Calibration Frequency
3. Operating Conditions of the instrument’s:
   • Wear & tear process
   • Frequency & severity of usage
   • Temperature & environmental exposure
4. Historical records of the measurement’s stability, consistency & accuracy
5. Specifications & Installation of your products & services

Risks of not Calibrating?
Calibration is an industrial standard to ensure the safety, quality and consistency of ISO 9000 & MS ISO 9001 manufactured products.

A measuring instrument’s reading cannot be assured; that can lead to inaccuracies with the overall product / service quality. Making it more costly to do the rework than the frequent cost of calibrating an equipment.

Choose the Right Heat Treatment Furnace

“Picking the most suitable furnace for industrial application require knowledge of the factors & processes needed for the manufacturing & production lines.“

An industrial furnace go up to 1000°C - 1200°C or higher. Allowing manufacturers to use for its heating & cooling capability on various materials (e.g. metals) to change their quality and properties to meet with industrial or market standards. 

   BENEFITS  

Why do manufacturers need such a high temperature?

1. Alter or fabricate the physical or chemical properties of a material.
2. Change the grain structure or mechanical properties of a material so that it becomes useful, serviceable and for human safety during and after the production line operations.
3. Making materials harder, stronger and more resistant to impact or softer and ductile.
4. Increase resistance to wear, tear, heat, corrosion, etc.
5. Improve electrical and magnetic properties (for metals)

One furnace cannot produce all of this characteristic or result as mentioned so manufacturers have to use different types of heat treatment methods and furnaces to achieve the desired results.

  FACTORS TO CONSIDER  

1. Purpose for which type of material needs to be heated
2. Source of heat and the Nature of heat transfer to the material
3. Heating by batch or continuously and the method of handling materials
4. Type of heat recovery
5. Other types of furnace classifications

  HEAT TREATMENT TYPE TO CONSIDER  

1. Preheating

• Helps to increase the temperature of the material slowly for the control of the thermal stress.
• Prevent or reduce chances of the material to crack, contract, or expand (from thermal stress).

2. Annealing 

• Removes thermal stress by heating up then slowly cooling down the metal.
• Capable of making the material softer, refine, or change its ductility or structure.

3. Hardening 

• Heats up the material with a high temperature and then follow up with quick cooling process (by quenching in water, oil, or molten salt) to increase material’s resistance to penetration (hardness).
• After this heat treatment, tempering or annealing can be used to slightly modify the material’s quality and characteristics.

4. Tempering 

• Involves slow and moderate heating to increase the hardness and toughness of the materials e.g. metals that have undergone previous heat treatment.
• Improve toughness, strength, plasticity, and impact strength of the materials (opposite of annealing) 

The above are only a quarter of heat treatment application available in the industrial market and methods.

Pendulum Impact testing is a type of mechanical testing used to study the toughness of a material to check the product's ability to absorb impact and to analyse the deformation process before fracturing (by using a falling pendulum weight or striker to determine a product's ductile to brittleness *).

*Common brittle testing samples are glass, wood, plastic, paper and dried clay (low toughness and can be deformed easily) while duxtile items are aluminium, copper, tin, mild steel, platinum and lead (high toughness and will not fracture easily).

Benefits of Pendulum Impact Testing

• Determine the material's ability to absorb energy during a collision by testing raw materials and molded components for strength and durability.
• Understand the impact strength, anti-fracture, impact resistance, degradation, damage of the materials and a product's lifetime responses to wear & tear.
• Prevents the future production quality failure (provide analysis for future designs)
• Investigate batch quality during the raw material’s creation.

  Common pendulum impact test methods :  

Both testing methods are used to check the impact resistance with the pendulum method but with some differences.

Charpy impact testing

• Test materials are placed horizontally 
• Hammer strikes at the middle point of the notch (surface) but in the opposite direction.
• Can test on metals, plastics and polymers.

Izod impact testing

• Test materials are placed vertically.
• Hammer strikes at the upper tip of the specimen.
• Can test on metals and plastics

How to Measure Colour for your Business

Having trouble with visual colour checking? Need accurate colour reading? 

Before colour is painted, printed and produced, manufacturers have to ensure that colour is monitored and accessed during the design stage, the formulation & production process and finally during the quality control process. Which determines the overall outlook on the products while attracting customers…

After the product assembly, final quality checks are done to identify and if needed, fix the colour issue. This is less expensive than doing rework on your goods after a rejection call.

There are many ways to identify & categorise colours, which includes:

Visually / Manually

• By comparing the product’s colour with a known standard (e.g. Pantone ®, Munsell, etc..)
• Open to errors and disagreement with your customers and suppliers. Because it requires properly trained people to visually evaluate color while doing it under different lighting conditions can affect assessments.

Using a colour meter or colourimeter

• A portable device that is able to read and provide tri-stimulus (RGB) values (uses an internal light source, to shine light down onto the surface of the sample and as it reflects back up to the device, it passes through three filters: red, green and blue), similarly to how our eyes see colours.
• Cannot detect metamerism (evaluating when two colors appear to match under one lighting condition but not when the light changes) rendering it unsuitable for all production applications e.g. formulation.

Using a spectrophotometer

• Works similarly to a colourimeter but instead of using only 3 filters (RGB values) there is 31 filters to measure the full colour spectrum value. These filters can measure light in each of 31 different wavelengths to determine the exact colour of a sample.
• Come in many shapes and sizes - small handheld devices, large benchtop workhorses and in-line devices used during manufacturing production.
• Ideal for identifying metamerism (evaluate how colour will look under different light sources
• Can measure almost anything from liquids, plastics, paper, metal, fabrics, etc.

“Even moisture levels of 0.07% can cause cosmetic problems on a part surface if the material is exposed to the temperatures of melt processing…” - Michael Sepe (independent materials and processing consultant)

Plastic Deformation (e.g. mould, holes, bumps, etc.) appears when plastic resins go through the production line without drying properly, thus affecting its overall quality.

(Above) Images of deformed plastic products i.e. spoon, bottle and panels.

How to get the unwanted moisture out? 

“In most plastics processing plants, resin dryers are a standard piece of equipment. Drying is a necessary preparative step to prevent this defect (material being moulded due too much moisture).” - Michael Sepe 

In order to avoid the moisture turning into air bubbles when going through the hot-melt extrusion machine, the resins has to pass through a drying machine beforehand to be preheated to get the moisture out.

​​

(Above) How a drying machine create pre-heating condition to release the moisture out plastic resins to create steam then rejecting the collected moisture away from the raw material.

Benefits of using drying machine: 

• Stabilises the production parameters 
• Reduce processing energy costs
• Ensure maximum polymer performance
• Preventing Cosmetic Problems aka splay or silver streaking.
• Preventing Hydrolysis (chemical reaction that breaks the covalent binds in the polymer chain, reducing molecular weight of the polymer and significantly reducing mechanical properties.)
• Preventing Part Failure (after drying, if the appropriate moisture for processing is not reached, premature part failure and structural defects can occur.)

CALIBRATION: ACCURACY & CONSISTENCY  

'It is better to record accurate or precise measurements?'

The Difference:

If you weigh yourself on a scale three times and each time the number is different, yet it is getting closer to your true (actual) weight, the scale is accurate.

However, when it comes to scales that provide precision, it can be precise but not 100% accurate. This would cause the measurements to be very close to each other and yet 'off' from the true value.

Some scales and balances do allow you to tare (by subtracting overall weight with the weight of the sample) or make simple adjustments (with reference of a standard weight) so that to make measurements both accurate and precise…

Many other measuring instruments will require more sophisticated equipment for calibration. e.g. Digital Thermometers often read precisly within a certain range but can also give increasingly inaccurate values outside of that range.

Hence, a proper calibration procedure that follow ISO 17025 standard is recommended.

When Calibrating:

• Record how far off its measurements are from known standard or true values.
• Keep a record of the calibration to ensure proper readings reference.

There are many specific equipment that requires periodic calibration to ensure accurate and precise readings.

3 REASONS TO CALIBRATE YOUR EQUIPMENT
       
“

1. Reduce Measuring Error of an Instrument

2. Cut Costs from Manufacturing Errors

3. Comply with the International Standard

Metallographic Welding Preparation

Around the 19th century, welding was introduced by joining sections of metal by forge welding (i.e. heating & hammering it). Today welding process like fabrication (for joining materials regardless of compositions, parts, shapes and sizes) are commonly used.
 

Aircraft & Aerospace, Shipbuilding & Marine, Land transportation / Automotive, Oil & Petrochemicals, Domestic & Metal Furniture are some of the well-known industries that uses welding. 
 

Since welds are usually made by different materials, it is important to choose the right metallographic preparation method to analyse its quality.
 

For Refinement, Research & Development and Analysis, Metallography is applied to access the different aspects in a weld e.g. depth of penetration, extent of Heat Affected Zone (HAZ), and other defects i.e. pores and cracks on representative work pieces. 
 

Proper preparation methods are needed to study the mircostructure and properties of the welded region.
 

Weld Microsections Examination Process :

Cutting / Sectioning : 

The first process of preparing the specimen for metallographic or microstructural analysis. After choosing the desired area of interest, sectioning and cutting will be applied.
 

To avoid deformation from cutting while lowering the risk of thermal damage on the cut surface:
 

 
Mounting : 
Mounting creates a mold around the specimens to provide protection and suitable & consistent sizes to be later used for the next preparation and examination steps.
 

Usually, macro sections for testing are unmounted due to time constraints, and the finish is usually adequate.

If semi-automatic preparation, then there are a number of specimen holders which will accommodate those sections from the welded joints. If mounting required there is an option of compression mounting.

It is not uncommon, weld examination have large cross sections. 


 

Electrolytic Polishing / Etching : 
After cutting and grinding, the specimens are later electrolytically polished and etched to provide a section suitable for macro examination. (To corrode or eat away the surface of top layer of the specimen; thus revealing the microstructures of the material for microscopic examination)
 

This provides:

• 1. Speedy and easy use of operation
• 2. Minimises user contact with acidic etchants
• 3. Capable of handling stainless steel types and other metal ls that are difficult to etch just chemically.

Macro sections

Depending on the hardness, parent material, heat affected zone, and metal welded of the specimen. A silicon carbide paper can make a specimen more suitable for macro etching and for weld macro examination later... 

The cutting life of the silicon carbide paper can last between 1.0-1.5 mins and this exacerbated (intensifies) with increased section size.

An alternative for grinding/fining for manual preparation, the Akasel Aka Piatto can offer:

Micro sections

The weld's material hardness can vary from one specimen to another. This is caused by phase changes during a welding, or because the joint has different metals incorporated in it. Sometimes a weld metal can contain age hardening (or particle hardening) or unexpected welding defect.

The preparation is important to ensure minimal polish relief between microstructural features and that all microstructural elements are retained for examination.
 

Semi-automatic or automatic preparation equipment for the wide range of welded materials; can provide consistency and reproducibility of the polish which can facilitates accurate microstructural analysis.
